It was a bit of a struggle but I finally have a scan I'm proud of! There were many more before this one but they had issues and weren't worth sharing. It was quite the learning experience along the way and learned a lot! I was beginning to lose faith in my setup but now I'm fully confident that it is worth sticking to it and not go seek out other alternatives!

I spent a bit of time getting my calibration panels to be a true 90 degrees. Out of the box they sat at 90.5...and yes, they are glass panels by HP.

Next I’m going to double check the spacing between the points on the panels...

Once the fusion process finished, I was blown away by the detail of the result. The STL file is nearly 1GB!

You can decimate that raw mesh down to about 50Mb and still keep that level of detail easily. I have taken 10Gb meshes and after decimation, cleaning and retopologizing have gotten them down to 30Mb, and the important detail is still nearly as good as the original mesh.
